Current State of Yttrium-based Superconducting Power Cable in Japan

Shinichi Mukoyama

Abstract — High temperature superconducting (HTS) power cable is expected to serve as a future power cable because of large power transmission capabilities, compactness, low losses and low cost. In particular, coated conductors hold potential to facilitate the implementation of the HTS cable for practical uses. We had studied the applicability of a coated-conductor to an HTS cable in the last NEDO project, and we verified that a coated conductor is a good choice for HTS cable. We report the current state of Yttrium-based HTS cable development in Japan, and we talk about the required specifications of the wires that we had found through experiments on HTS cables.
